"Happy Father's Day to the best Dad I could ever ask for who taught me everything I know," the drummer began his June 18 Instagram post. "My kids, I'm so blessed to learn from you and be loved by you. Being your father is the best thing in the world. You're my best production yet and I'm so proud to be your father. I love you Alabama, Landon and Atiana."
The 47-year-old concluded his note with a shout-out to his and Kourtney's baby, writing, "And thank you god for my future blessing."
